PEKING REPORTED ARMING ZANZIBAR

NAIROBI, Kenya, June 14— A shipment of Chinese Com­ munist arms was reported to­ night to have arrived on Zanzi­bar.

The shipment was understood on the highest authority to have contained subMachine guns and other automatic weapons. Sources close to the island had no immediate in­ formation on the size or the full scope of shipment, but said it included a “number of crates.”

Mr. Karume added further confusion to events on the is­land by first announcing that weapons and ammunition would be issued today to all “freedom fighters” who took part in the island's revolution last Jan­uary because “counterrevolu­tionaries” were at work on Zanzibar. But he called off the
